        self.text.place(y=220)
    def Get(self):
        try:
            host = self.entryPop.get()
            port =int(self.entryPort.get())
            user = self.entryUser.get()
            pw = self.entryPass.get()
            fromaddr = self.entryFrom.get()
            toaddr=self.entryTo.get()
            subject=self.entrySub.get()
            text = self.text.get(1.0,tkinter.END)
            msg =("From:%s\nTo:%s\nSubject:%s\n\n"
                  % (fromaddr,toaddr,subject))
            msg = msg+text
            smtp=smtplib.SMTP(host,port)
            smtp.set_debuglevel(1)
            smtp.login(user,pw)
            smtp.sendmail(fromaddr,toaddr,msg)
            smtp.quit()
        except Exception as e:
            self.text.insert(tkinter.END,'发送错误\n')
root =tkinter.Tk()
window=Window(root)
root.minsize(600,400)
root.mainloop()
